I was able to find one, head only. IMO, Its borderline NON conforming. :)
I installed a KK XT 60s which is a low launch/low spin shaft and this combo shoots mid trajectory missles for me.
Very Long and forgiving. Its not as soft feeling or sounding as my trusty Epon 153 but thats not to say that this is harsh in any way.
Only 358 made so it'll be a hard one to find. Might even be Unicorn status.
Good Luck!
FYI .350 bore size so a shim was needed.
